The Mobile Library
http://handybibliothek.qioo.de/books_en.php

The Mobile Library is where you can download english mobile books. In most cases you need only the JAR-file. Save files in separate folder because each mobile book has the same file name. After installation an individual name is given. Alternatively you can download the JAD-file over the air. In most cases this is the most convenient way to install a mobile book. You can do so by entering the following URL in the WAP-Browser of your cellphone (please note: you will be charged for the GPRS/UMTS-traffic caused by the file download): http://www.handybibliothek.de/index.wml.
